Would it be accurate to say that the only thing keeping a series I PL model 700 from being converted into FC version of a WOPL as of today being the lack of available cooling fins?

I don't think Joe's back planes fit the 700?? All Lee's 700s here have fins like the 700Bs. I think you can do them WO quasi. I think Jer did one last year like that?

The transistor hole patterns are different so the backplane boards won't line up with the existing chassis and heat sink holes. I have a 700 Series I too and found out from Lee and Joe that the patterns don't match. You can get a chassis from Joe but no heat sinks as of yet.

That was my understanding. I just need to find a source for fins and I'm good to go, capice?

I've already got a quasi WOPL, want to try an FC down the road.

My recollection is you need 700B fins along with Joe's new replacement 700B chassis and your good to convert.

One thing you can , and what I am going to do to mine, is upgrade the control board the white oak along with new power caps and transistors. You can at the same time change the existing backplate components to full complimentary , not to hard to do. That will give you a kick ass amp. My dad bought this series one on or about 1970 and I still have it.

You'd think after all those I made I would have....but alas...I did not. Joe had to plot those to build the chassis. Perhaps he has a drawing that might be of some help....?

I love the sound of WOPL in the morning

I have a 700 series I about to be on the workbench. Would love to try and rewire for full comp with a new white oak board. We have any details on how to wire the backboard? I thought I read in another thread someone doing it. Just can't find it.
